Many Ford truck calipers use a phenolic piston in the caliper. A combination of the differences in material, corrosion, build up of crud between the piston and caliper, and it seizes when it gets hot. I have had this happen twice on my '91 Ranger in the interstate traffic in Atlanta when the calipers get high mileage (100k). Allowing them to cool frees them up. I replace them after this happens.
